Material of the profile to be extruded plays an essential role in determining process parameters and potential limitations of a process. For example, minimum thickness of extruded carbon steel sheet is 3mm whereas same sheet of aluminium can be extruded into minimum sheet thicknesses of 1mm.
DFM stands for design for manufacturing, so as the name suggest the design is manufacturing friendly, in simple terms design that can be manufactured easily and cheaply. DFM guidelines define a set of rules for a person designing a product to ease the manufacturing process, reduce cost and time.
Examples of T-slotted profiles 1964 patent demonstrating early use of extruded T-slot members. Cross-section of 80/20 T-slotted profiles, 10 and 15 series A bicycle trailer for bike-trekking with three Euroboxes and aluminium profile framing
A horizontal hydraulic press for hot aluminum extrusion (loose dies and scrap visible in foreground) There are many different variations of extrusion equipment. They vary by four major characteristics: [1] Movement of the extrusion with relation to the ram. If the die is held stationary and the ram moves towards it then it is called "direct ...

Extrusion is a manufacturing process used to make pipes, hoses, drinking straws, curtain tracks, rods, and fibre. [1] The granules melt into a liquid which is forced through a die, forming a long 'tube like' shape.
Material extrusion-based additive manufacturing (EAM) represents one of the seven categories of 3D printing processes, defined by the ISO international standard 17296-2.. While it is mostly used for plastics, under the name of FDM or FFF, it can also be used for metals and ceram
Die design is critical because of the large forces required. To reduce the friction of the pushed sample is lubricated with grease for example mixture of graphite and oil, [ 5 ] and to reduce the forces, the process is sometimes carried out at elevated temperatures but then recrystallization can occur which can also leads to excessive grain ...
